Title: Improvements relating to adhesives
IPC: C08J5/12
Filed: 1980-05-28
Abstract: For improving the adhesion of leather or rubber to a surface of the same or a different material, a solution of a complexing agent comprising both a sulph-hydro group and a carboxylic acid group, in particular ammonium thioglycollate, is applied to both surfaces which are to be joined and is incorporated in a conventional adhesive which is then used to make the joint. For leather, it is preferred to use an alkaline aqueous solution of the complexing agent, which may be prepared by neutralising thioglycollic acid with ammonia. For rubber, a non-aqueous solution prepared by neutralising thioglycollic acid with ethanolamine is preferred.

Title: Control of electrical devices
IPC: H02J3/14
Filed: 1981-06-09
Abstract: A control arrangement for regulating the power supplied to two electrical heating elements (1a, 1b). A ripple counter 4 is clocked at mains frequency and selected output signals therefrom are utilised by logic circuits (20, 30) to stagger the turn on and turn off times of the heaters, during an initial warm up period. A part (4') of the counter (4) is used as a four bit up/down counter and the signals generated thereby (at 1.27 sec. intervals) are converted to analogue form and fed to a comparator (10). When the input level to the comparator exceeds a preselected level a further control signal is generated which, after the initial warm up period, actuates a further logic control counter (40) to cause one or other of the heating elements to be turned on. The heating elements are preferably turned on consecutively in interleaved manner. <IMAGE>

Title: Telephone subscriber's instrument circuit
Inventor: BLOMLEY PETER FRED
IPC: H04M1/60
Filed: 1982-03-25
Abstract: A telephone subscriber's instrument circuit includes a dynamic microphone which is coupled via amplifiers to the line terminals (L1, L2). These latter are also coupled to the receiver transducer via further amplifiers. In addition the circuit is line powered in such a way as to be polarity-insensitive. The circuit includes a four- transistor bridge amplifier (T1, T2, T3, T4), which functions as a bidirectional speech amplifier between the line and the instrument's circuitry. This amplifier includes two transistors (T1, T2) each with its collector connected to a different line terminal (L1, L2), the emitters of these transistors being connected together and to a resistor (R1) across which is developed a direct voltage for powering the circuit. This voltage has the same polarity whichever of the line terminals is positive. In addition there is a storage capacitor (C1) connected to the resistor to provide DC during momentary line breaks (e.g. due to dialling). The characteristics of the circuit are such that it is adequately powered even with a low impedance telephone connected to the line in parallel with it. <IMAGE>
